【摘要】 通过高强复合骨料混凝土和基准高强混凝土的对比试验表明,复合骨料混凝土的自收缩能显著降低。尤其对于含硅灰或矿粉的混凝土,复合骨料降低混凝土的自收缩效果更好。更多还原

【Abstract】 Through comparative test with reference concrete , the auto-shrinkage of concrete with composite aggregate can reduced significantly . For concrete containing silica fume or ground slag , the reduction of auto-shrinkage is more effective by composite aggregate . The measuring instrument of concrete auto-shrinkage is designed by oneself .更多还原
